Full Discussion: limit telnet
Operating Systems SCO limit telnet Post 302083154 by hegemaro on Friday 4th of August 2006 10:22:25 AM

tcp_wrappers will do the trick nicely. The software allows you to limit IP access based on service. I believe it comes standard with SCO but if not, it is available from ftp://ftp.porcupine.org/pub/security/index.html complete with documentation.

Try searching your man pages for "wrapper".

I'd give more details but it's been so long since I've used them. I hope this starts it.

kf

KF(1)							    BSD General Commands Manual 						     KF(1)

NAME

     kf -- securely forward tickets

SYNOPSIS

     kf [-p port | --port=port] [-l login | --login=login] [-c ccache | --ccache=ccache] [-F | --forwardable] [-G | --no-forwardable]
	[-h | --help] [--version] host ...

DESCRIPTION

     The kf program forwards tickets to a remote host through an authenticated and encrypted stream.  Options supported are:

     -p port, --port=port
	     port to connect to

     -l login, --login=login
	     remote login name

     -c ccache, --ccache=ccache
	     remote cred cache

     -F, --forwardable
	     forward forwardable credentials

     -G, --no-forwardable
	     do not forward forwardable credentials

     -h, --help

     --version

     kf is useful when you do not want to enter your password on a remote host but want to have your tickets one for example AFS.

     In order for kf to work you will need to acquire your initial ticket with forwardable flag, i.e.  kinit --forwardable.

     telnet is able to forward tickets by itself.
